Bests & Worsts Reviews from Amazon

Before I took the plunge and bought this lens, I was a total Canon snob. I didn't think that there was anything superior to a canon lens. Before purchasing this, my favorite lenses were the Canon 135mm f/2L and the 50mm f/1.2L. I love how creamy and beautiful the depth of field was on both lenses when shooting wide open. And, to me, both were very sharp. But, after receiving the Sigma 35mm and doing some micro adjustments, I realized that this lens FAR surpasses any Canon lens I own. It is SHARP. Holy crap it's sharp. I've used a lot of different lenses and this lens produces the sharpest and most visually pleasing portraits. I tend to shoot at f/2 for portraits with this lens, but even when I open it up more, it's still super sharp. If you're on the line about buying a Sigma over a Canon, don't be. Definitely buy this lens right now. From now on, I will be looking at Sigma ART lenses before I even think about buying another L series lens. Super happy with this purchase.
